Definitions

  • the invention relates to a steam-heated roller with a Boiler room arrangement over a feed connection arrangement can be loaded with steam.
  • the invention has for its object the drainage option to improve the roller.
  • This task is the case of a steam-heated roller type mentioned solved in that they have a Has pump arrangement for pumping condensate applies a pressure counteracting the centrifugal force.
  • a Pump arrangement can significantly increase pump performance Provide less loss and more effectively than the slip steam. This keeps the energy losses smaller.
  • the pump arrangement can be independent of the steam pressures work in the roller so that an effective Drainage even at low steam pressures and high ones Working speeds are possible.
  • the pump arrangement is particularly able to remove the condensate pushed radially outwards due to the centrifugal force will pump back inside so that it has a centric line can be removed.
  • the pump arrangement basically just has to be interpreted that way that the condensate against centrifugal force can pump out.
  • the pump arrangement is preferably relative to the roller arranged immobile. So she turns with the Roller with. This eliminates seals between moving Parts, namely the roller and the pump assembly. Rather, these remain aligned with one another in operation, so that rigid connecting lines to and from the Pump can be provided.
  • the pump arrangement is arranged on an end face of the roller.
  • the Pump arrangement is so as a separate component or as formed separate component group, for example is flanged onto the roll neck of the roll and accordingly rotates with the roller.
  • the Pump arrangement not directly on the actual one Be flanged. You can also on the axial Be placed outside of the roll neck where it surrounds the stub.
  • the pump arrangement requires practically no additional installation space and bothers otherwise the normal operation of the roller.
  • the pump arrangement preferably has at least one Pump with an externally operable drive element on. If the pump can be driven from the outside, then must there are no drives inside the roller. It is only necessary to drive means from the outside to let the drive element work. So that will be Weight and moment of inertia of the roller are kept low.
  • the drive element preferably acts upon rotation of the Roll together with a stationary drive assembly.
  • the pump arrangement is thus driven by the Relative movement between the rotating roller and the Drive arrangement. Although this means that to drive the roller requires a slightly higher output is. However, this is negligible. For that gets you have a relatively simple drive option for the pump arrangement.
  • the drive element advantageously has a reset device on. Then there is one for driving higher force required because the counterforce of the Reset device must be overcome. Training but has the advantage that the drive only in one Direction must act, for example the drive element must push in or pull out.
  • the pump arrangement advantageously has a piston pump on.
  • a piston pump can be done with relatively little effort apply the necessary pressures to the centrifugal force or counteracting centrifugal force.
  • a Piston pump can also be relatively simple press in which the drive element radially inwards and is moved out. For the desired area of application a piston pump is sufficient.
  • the piston pump has a piston having an inlet control edge and / or an outlet control edge having. So with the piston can not only the pump function can be realized, but it the control function is also implemented in such a way that, for example, the inlet during a piston stroke is closed automatically, so that in the cylinder space liquid penetrated only through the outlet can escape, but not through the inlet again is pushed back.
  • the outlet control edge can be at one Return stroke of the piston to close the outlet so that once liquid has been pumped, it will not return can.
  • the pump arrangement has a circumferential peripheral surface and the drive arrangement from the outside of the pump assembly acts.
  • the pump arrangement consists of a ring construction on an outer pitch circle is equipped with several pumps or pump segments.
  • the drive arrangement then sees itself during rotation the roller of an essentially unchanged counter surface exposed, namely the radial outer wall of this Ring structure. So no precautions need to be taken to avoid protruding parts. The only thing that protrudes are the drive elements of the pumps that rotate radially inward and be moved out.
  • the drive arrangement has a drive surface which in Circumferential direction a changing distance to Has pump arrangement. If the drive surface in a peripheral portion of the pump assembly of the pump assembly approaches, then the drive element becomes radial pressed inwards. If in another Circumferential section results in a greater distance, then can the drive element can be extended again. Since the Pump arrangement all at one revolution of the roller Passes through circumferential sections, it is ensured that at least once with each rotation of the roller Inward movement and once an outward movement of the Each pump is driven by drive elements. If the pumps the pump arrangement evenly distributed in the circumferential direction then a pump is always "active", i.e. she is pressed. The remaining pumps will then be in line after actuated.
  • the drive surface is movable and essentially the same peripheral speed how the pump assembly has.
  • the drive surface rotates with it the pump arrangement with, so that there are relative movements limit that the drive element on and is extended. This arrangement helps to prevent losses and above all to keep wear down.
  • the drive surface is preferably through a peripheral surface a wheel formed.
  • the wheel can be about its Turn axis. So if a drive element of a pump comes into contact with the peripheral surface of the wheel, then the wheel can be turned. The initial one Contact between the drive element and the wheel take place where the drive element is extended Distance between the wheel and the pump assembly still is relatively large. Upon further rotation of the pump assembly the distance between the Point at which the drive element rests on the wheel, and the pump arrangement until the smallest Distance is reached at the location by a through degrees and the centers of the wheel and roller the peripheral surface of the wheel is formed. Then enlarged the distance again and the drive element the respective pump can extend. You can use the bike arrange so that its peripheral surface is a small distance to the pump arrangement. However, it is preferred when the peripheral surface of the wheel on the pump assembly is applied.
  • the wheel is driven is and via the pump arrangement with the roller in torque transmitting connection is.
  • the drive of the wheel keeps slip losses small when the peripheral speed equal to the peripheral speed of the Pump arrangement is. This will also wear out kept small. If the wheel is still in torque-transmitting connection to the roller, then you can also use this wheel to drive the roller use in total.
  • the wheel can, for example be designed as a friction wheel. But it can also over a toothing with a corresponding counter toothing are connected to the pump arrangement.
  • the gearing can be arranged in the axial length range be where the pumps are located, or axially to it added.
  • the drive surface be formed by a belt that the pump assembly wraps around part of its circumference and via a deflection roller arranged outside the pump arrangement is led.
  • a movable drive surface is designed so that they have a small radial distance on a peripheral region for pump arrangement. The distance is zero here because of the belt on the pump assembly is applied. In the area where the pulley is placed the distance increases again, so that the drive elements of the pumps can be extended.
  • the pump arrangement advantageously has at least a rotary pump for pumping out condensate.
  • Rotary pumps work in contrast to piston pumps with rotating and / or orbiting working elements. This has the advantage that the mass distributions change very little during operation. This leads to one largely unaffected by the operation of the pump arrangement Run the roller, which is especially true at higher Speeds is an advantage.
  • the rotary pump preferably has at least one externally operable work element. If the Pump can be driven from the outside, then you have no drives provide inside the roller. It is just required, external drive means on the working element let it work. So that the weight and keep the roller's moment of inertia small. in this connection the pump arrangement can be immovable relative to the roller be arranged. So it rotates with the roller. This eliminates seals between moving parts, namely the roller and the pump assembly. These remain rather aligned with each other in operation, so that rigid connecting lines to and from the pump are provided could be.
  • a pump inlet and a pump outlet are advantageous constantly separated by the working element.
  • valve control can be dispensed with.
  • the working element advantageously runs with one revolution at least one work area, it being in a working chamber with a constant volume moved from the pump inlet to the pump outlet.
  • the Liquid that gets to the pump inlet also gets there into the delivery chamber.
  • the delivery chamber which itself moved by the working element, it is from the pump inlet conveyed to the pump outlet. Because the volume of the Delivery chamber is constant, there is no compression, so that even non-compressible liquids are promoted can be. Since liquid is continuously added the liquid in the pump outlet continues displaced and pushed radially inwards.
  • the rotary pump is preferably a vane pump educated.
  • a vane pump has an eccentric working element mounted to a housing that has radially retractable and extendable wings.
  • the working element is thus designed as a vane wheel. If the vane wheel rotates, then arise in the area where the vane wheel is one has a greater distance from the housing, the corresponding Feed chambers.
  • the rotary pump be designed as a centrifugal pump with a fast rotating impeller works. Because the pump inlet over one opposite the axis of rotation of the roller outwardly inclined duct connected to the steam supply is, the condensate that is formed is Effect of centrifugal force promoted to pump inlet, is pending with a certain form. The Pumps don't even have to be self-priming, but under the effect of this pressure with the Condensate filled.
  • the working element preferably acts when the Roll together with a stationary drive assembly.
  • the pump arrangement is thus driven by the Relative movement between the rotating roller and the Drive arrangement.
  • the working element preferably stands with a drive wheel in a torque transmitting connection, the with a counter wheel in positive or frictional engagement stands, whose axis coincides with the axis of rotation of the Roller matches.
  • the drive wheel can either rest on the counter wheel so that when moving of the drive wheel via the counter wheel due to Friction a rolling of the drive wheel on the counter wheel results, or it can be in the drive wheel and the counter gear is two gears that work together comb. So if the drive wheel is guided around the counter wheel becomes what happens when the roller rotates in the Usually the case, then the drive wheel is corresponding the ratio of the circumferential lengths of the drive wheel and counter gear rotated and thus drives the working element to a rotational movement.
  • the counter wheel is rotatably arranged to the bearing housing of the roller. This results automatically when the roller rotates the drive of the working elements of the pump arrangement.
  • the counter wheel be rotatably arranged with respect to the bearing housing and have a drive. It is then possible through a suitable control of the drive to accelerate the counter wheel or brake to that of the pump assembly control the amount of condensate discharged.
  • the work element have a steam engine.
  • the flowing one Heating steam which in addition to its thermal energy in the Usually also has a certain pressure then drive the work element directly or indirectly.
  • the resulting "steam losses" are low and can be accepted.
  • the steam flowing through with the condensate to be pumped or through additional holes in the pump chamber get there and with the help of the wing cells Drive vane wheel (or act on the blades) ,
  • the working element is preferably torque-transmitting Connection to a turbine wheel that with steam flowing through it.
  • the boiler room arrangement is preferably a plurality formed by peripheral channels.
  • Such rollers are also referred to as "peripherally drilled rolls” even if the channels are not through holes, but on other ways have been formed.
  • the channels that are are located relatively close to the surface of the roller, direct the steam to where it gives off its heat should. At the same time, it also becomes a channel structure given for the condensate, making it easier is to collect and drain the condensate.
  • the pump arrangement is preferably over at least a condensate inlet line with the radially outer one Wall of the boiler room assembly connected.
  • the condensate inlet line is right there with its beginning arranged where the condensate is due to the centrifugal force will collect during operation of the roller. This makes it easier the removal.
  • Each channel preferably has an end face Dining room open and the condensate inlet leads from Dining room.
  • the dining room serves first of all a connection between the steam supply line and the Channel. You can now add this dining room still use to collect the condensate and to be given to the condensate management.
  • a dining area is preferably assigned to several channels. This not only facilitates the supply of steam the individual channels. The steam distribution can then namely, relatively evenly on all channels. The number of pumps can also be reduced. It is no longer necessary for each channel to have its own pump is assigned, although this is of course possible. You can see the individual pumps in the circumferential direction distribute evenly and a dining area for each pump provide.
  • the dining area is designed as an annular space and connects all channels together. This will create a ensures a very even distribution of the steam. At the same time, however, one becomes the same uniform discharge of the condensate ensured.
  • the condensate inlet line to the pump preferably rises radially outwards. In operation it results then a pre-delivery of the condensate by the Centrifugal force is pressed outwards and thus to the pump is promoted.
  • the pump therefore has to be practically none Provide more suction power.
  • the pump is preferably via a non-return valve connected to an outlet line which with a line section guided by a pin of the roller connected is. If the pump the condensate via the anti-return valve, for example a Check valve, has pumped out, then there is for the condensate no longer under the effect the centrifugal force to get out again. Thereby the operation of the pump becomes very reliable.
